I just reopened my pool and already shocked all the algae to death. I have a crappy wal mart strip tester so you will have to forgive me on some of these readings. My Chlorine levels are very high and the hardness seems to be ok, however, my TA is very low around 40? My pH is also low around 6.8 or maybe lower. My stabilizer is currently low too but I'm using the 3" tablets and my pool is covered. I have already added 12lbs of Baking Soda and 18lbs (4.5 boxes) of Borax and nothing seemed to have changed. Am I forgetting to do something before adding all these things in? My pool is ~17,000 gallons.
